To all w hom 'it may coa-cern:

Be it known thatl l, GEORGE F. ALLEN, a citizen of the United States7residing at Oronogo, in the county of Jasper and State of Missouri, haveinvented certain new and useful improvements in Hydrocarbon-Uil Burners;and I do hereby declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in theartl to which it appertains to make and use the same.

This invention relates to hydro-carbon oil burners and it consists inthe novel features hereinafter described and claimed.

An object of the invention is to provide a burner of the characterstated which is of simple and durable structure and having its parts-soarranged as to economically consume mixed steam and hydro-carbon oilwhereby a hot llame is produced.

lVith the above object in view the burner comprises a pipe closed at oneend by a cone shaped tip having an outlet at the apex of the cone, avalve casing is applied to the other end of the pipe and a valve ismovably mounted therein. A needle valve is carried by the firstmentioned valve and is adapted to operate at the opening in the cone andvalvein the casing adapted to operate and control the flow of oilthrough the valve casing and pipe. The pipe is adjustably mounted. in ajacket into which the steam is admitted whereby the pipe is surroundedby a volume of steam7 the nozzle is mounted upon the jacket and includesa pod from which the said cone shaped tip is spaced and with relation towhich the said pipe may be adjusted to increase or diminish the saidspace. A; burner tip is mounted upon the nozzle and the said tip ispreferably provided with a diametrically disposed slot outlet openingthrough which the mixture of steam and oil may pass and at which pointthe mixture is ignited producing a broad flat flame.

In the accompanying drawings :W

Figure 1 is a side elevation of the burner.

Figure 2 is an enlarged longitudinal sectional view of the body of theburner.

Figure 3 is a similar view of the burner nozzle.

Figure 4 is a transverse sectional view through the burner.

Figure 5 is a perspective view of the burner tip.

Figures 6 and 7 are cross sectional views of burner pipe connections. i

As illustrated in the accompanying drawing, the burner comprises a ypipe1 which is preferably of brass or other suitable material which willreadilycnduct heat. rThe pipe 1 is closed at one end by a cone shapedtip 2 having an outlet opening 3 at the apex of the cone. The saidoutlet opening is in alinement with the axis of the pipe 1. A valvecasing 4 is screwed upon that end of the pipe 1 which is opposite theend at which the tip 2 is located and a valve stem 5 has screw threadedengagement with the casing 4 whereby vthe said v'alv'e stem movesvlongitudinally as it is turned in a usual manner. valve 6 isv carriedat the inner end of the stem 5 and may close against a seat 7 providedat the inner surface of the casing 4. A needle yvalve 7 is attached tothe valve 6 and is disposed along the axis of the pipe 1. The pointedend of the needle valve 7 is located at the opening 3 of the tip 2 andmay be moved toward or away from-the same as the stem y5 is turned andat the same time that the valve 6 is moved toward or away from the seat7. An oil supply pipe 8 connects with the side of the casing 4.

A jacket 9 surrounds the intermediate portion of the pipe 1 and isspaced from the exterior thereof. The said jacket is provided at itsside with a steam inlet port or opening 10. The jacket 9 is closed atone end by a head 11 which has screw threaded engagement with theintermediate portion of the pipe 1 and a nut 12 is threaded upon thesaid pipe 1 and bears at its face against the end of vthe head 11 andserves to hold the parts in the position to which they are adjusted.

A nozzle is applied to the opposite end of the acket 9 and the nozzleincludes a head 13 which is screwed upon the jacket 9. A sleeve 14 isscrewed into the outer end of the head 13 and its axis is in alinementwith the axis of the pipe 1 as the said pipe 1 is adjusted within thejacket 9 as hereinbefore indicated the tip 2 is moved toward or awayfrom the inner end of the sleeve 14 and consequently the space betweenthe inner end of the sleeve and the cone shaped tip inay be increased ordiminished as desired. A nipple l5 is screwed into the sleeve le and acollar 16 is screwed upon the outer end et the nipple A -nurner tip 1'?is screwed upon the collar l@ and is provided at its outer end Wil/ii adieinetrically disposed slot ln operation the hydro-carbon oil isadmitted into the pipe l through the casing 4i and trein the supply pipe8 when the valve 6 is at an open position 'with 'l seat 7. it the sainetime l into the jacket 9 through Consequently the inten ot the pipe lwhich con- Y surrounded hy a volume of ino inas'nuch as the said portionot i pipe is thereby heated the oil is converted from a liquid into avapor. This vapor escapes troni he pipe l through the opening 3 o thetip 2 and iniXes With the steam which passes l through the head 13 andis sprayed into the oil through toe space hetween the tip 2 and theinner end of the sleeve 14:. rllhis inixture passes through the nipplel5 and the tip l? and out thii'oug'h the slot 1.8 Where it is ignitedand burns in a torin ot a broad flat thin flan/ie.

llt is apparent that hy adjusting the pipe l with relation to the sleevele that the amount of steam Which is admitted into the vaporized oil maybe regulated. lt is also apparent that by adjusting the needle valve 7with relation to the opening 3 in the tip 2 that the quantity ofvaporized oil which is admitted to the steain inay he regulated.

Furthermore it Will he apparent that the adjustment ot the valve 6 withrelation to the seat 7 controls the quantity oi' liquid oil which passesthrough the casing` 4 into the pipe l.

Having described the invention, what is claimed is A hydro-carbon burnerincluding a casingv having a valve seat, means of 'fuel supply leadinglto said casing, a valve in said casing cooperating with said seat tocontrol the supply of fuel therethrough, a iiuel supply pipe leadingY tosaid casing, a tip in the outlet end of said pipe, a needle extendingiroin said valve and cooperating With tip as a valve therefor9 a jacketabout said pipe in communication with a source ot fluid supply, a headengaging said pipe and said jacket, a nozzle for said jacket having` aconstricted end disposed in advance of said pipe and jacket7 a sleevedisposed in said constricted portion, and a burner nipple extending fromsaid sleeve.
